This product is a function module of the Series 20 from Telecom Behnke, specifically designed as a keypad module for door intercom stations. It serves as an additional component to the base electronics and enables the use of code lock and telephone functions. The module is made of aluminium and features 16 keys for entering access or call codes. The keys are unlit, requiring sufficient ambient lighting for operation. The module is designed for electronic systems that do not use flat ribbon cables, making it suitable for existing installations of Series 20 based on this technology.

Keypad module
The keypad module provides 16 mechanical keys intended for entering numeric or code combinations. These keys are not illuminated, meaning operation is not possible in dark or poorly lit areas. The keys are arranged in a matrix designed for clear and quick operation. The keys are robust and designed for use in industrial or commercial environments where high mechanical durability is required.

Functions and equipment in detail
The module enables, in conjunction with the base electronics of Series 20, the use of code lock and telephone functions. The code lock function allows access to protected areas by entering a pre-set code. The telephone function enables communication over the integrated telephone network, with the connection established via the base electronics. The module is not autonomous and requires integration into an existing Series 20 system.

Technology explained simply
The module consists of a housing made of aluminium, providing high mechanical stability and corrosion resistance. The use of aluminium ensures long service life and good heat dissipation, which is particularly important during continuous operation. The keys are mechanically operated and unlit, minimizing energy consumption. The module is designed for systems without flat ribbon cables, meaning it is compatible with conventional cable connections used in older or special installations.

Compatibility and accessories
The module is specifically developed for door intercom stations of Series 20 from Telecom Behnke and requires use with the base electronics of this series. It is not suitable for other systems or manufacturers. Compatibility is limited to systems without flat ribbon cables, enabling use in certain existing installations.

Mounting and installation
Mounting is performed at the door intercom station of Series 20, where the module is integrated into the existing housing. Wiring is done via the existing connections of the base electronics, ensuring the use of cables without flat ribbon cables. Installation does not require special tools, but proper wiring and securing are necessary to ensure stable operation.

Advantages in operation
The module provides a reliable and robust solution for access control and communication in commercial or industrial environments. The use of aluminium ensures high mechanical strength and longevity. Integration into existing Series 20 systems allows for easy expansion without extensive modifications. The keys are designed for frequent use, enhancing operational reliability.

The product is delivered in the colour silver, offering a neutral and professional appearance. The surface is smooth and easy to clean, which is advantageous for hygiene requirements in certain areas. The keys are clearly visible and enable intuitive operation.
